This invention relates to improvements in bobbins usable more particularly in multi-..

color magazines and it is the general object of the invention to provide means for resisting the tendency of bobbins to rotate on their axes as they await transfer.

In the ordinary stationary magazine the reserve bobbins as they await transfer are" stored in parallel vertical stacks and move downwardly by gravity toward transfer position. It is found that due to'the vibration of the loom the bobbins tend to turn on their axes and cause either undue slackness or tightness of the filling which extends from the bobbins to the thread holder. It occasionally happens in a magazine of this type that at the time of transfer the filling will be broken and as a result the loom will be stopped by the filling stop motion. It is an important ob-;

ject of my present invention to provide a bobbin so formed that when cooperating with other bobbins of similar type rotation will be prevented.

It is a more particular object of my invenportion which is substantially square in cross,

section so that the wound mass of weft will have flat sides, the periphery of the bobbin and consequently the length of yarn wound thereupon being somewhat greater than is the case with bobbins circular in cross section.

With these and other objects in view which will appear as the description proceeds, my in vention resides in the combination and arrangement of parts hereinafter described and set forth in the claims.

In the accompanying drawings wherein I have shown an embodiment of my invention,

Fig. 1 is a vertical transverse section through a two color stationary magazine having bobbins made according to my present invention stored therein,

Fig. 2 is a side view of the bobbin before being wound,

Fig. 3 is an end view of'the bobbin taken in the direct-ionof arrow 3, Fig. 2, and

. Fig. 4 is a transverse sectionperpendicular tothe axis of the bobbin through the latter when woundfwith' a mass of weft.

Referring toFig. 1, I have shown a convenient type of magazine for illustrating my invention, said magazine having; an inner plate 10 provided withparallel spaced ribs 11 which define vertical 7 compartments Cradles 12 are located at'the; bottoms of the stacks'or compartments 0 and when rocked by mechanism not shown act to pass the lowest bobbin B of the corresponding stack from the latter down the inclined supports 13 toward transfer position.

The ends of the weft from the reserve bobbins are led to athread holder not shown.

The particulartype of magazine which may be used in connection with, my improvedbobbin forms no part of my invention and may be of the usual construction.

In carrying my invention into effect I alter the shape of that part of the bobbin B on whichthe mass of weft is wound. Thebobbins will ordinarily have heads 20 provided with the usual rings 21' and will'have a substantially cylindrical feeler or weft detector engaging portion 22. Thereduced end of the bobbin-extending toward the tip T is made preferablysubstantially square'in cross section asindicated in Figsai and 4. While I have shown a cross section ofthis particular fornryet'I do not wish tobe limited to the squareas any other formgwhich willpresent a non-circular "outline in cross section will sulfice, the important feature being that the diameter of the bobbin measured in one direction will be of a different magnitude than the diameter measured in another direction. It is preferable to have the tip end T of the bobbin round as indicated at 23 to facilitate unwinding of the weft.

By an inspection of Fig. 4 it will be seen that the wound mass of weft W will have contact with corresponding portions of adjacent bobbins.

In the operation of the magazine the bobbins are constrained to move about their axes but with the flat areas F of adjacent bobbins in contact with each other this tendency is resisted with the result that the bobbins pass down the compartments with practically no angular movement about their axes and the aforesaid tightening or slackening of the lilling which extends to the thread holder does not occur. 7

From the foregoing it will be seen that I have provided a bobbin the wound mass of which has a section of non-circular form the effect of which is to prevent the rotation of bobbins as they await transfer in the maga- Zine. It will also be seen that the perimeter of the bobbin will be increased'and therefore the amount of yarn which may be unwound thereon is greater than would be the case if the bobbin were cylindrical in cross section.

Having thus described my invention it will be seen that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention and I do not wish to be limited to the details herein disclosed, but what I claim is:

1. In a weft replenishing mechanism, spaced walls forming a compartment along which bobbins may move towards transfer position and a plurality of superposed bobbins in said compartment, said bobbins being of non-circular section and when wound having outer yarn surfaces of similar non-circular outline engaging each other to resist relative angular movements in said compartment.

2. In a weft replenishing mechanism, substantially vertical spaced walls defining between them a compartment along which bobbins may move toward transfer position, and a stack of superposed bobbins in said compartments, each bobbin being so formed as to have substantially flat horizontal outer yarn faces when wound, which faces engage each other to resist relative angular movement of the bobbins.

In testimony whereof I have hereunto afiixed my signature.
